go to www.dfi-street.com
and ask those fellas. There are guys from all over the world there, who are incredible with their knowledge on compatibility. It is actually a DFI forum, but I bet someone would know something about it. Good luck.
Oh yeah, I have 2 gig of G.Skill, not the same model and make that you have, or the same speed. But, the memory is good for overclocking. G.Skill specifically makes their RAM modules for people who want to overclock. So, if you aren't going to OC, don't bother. The reason the stock speeds are so low, is because they make them to have room for OC'ing. It is actually very very good RAM. They have been tested by some of the best OCers in ASIA.
